CAN-FILLING i MACHINE.

To all why'e mag/concern:

Be it imown that I, VVAL'mR J. PHELPS, a citizen of the United States,residing at Baltimore, State of Maryland, have invented a new and usefulCan-Filling Machine, of which the following is a specification,

This invention has reference to improvements in'can filling machines,and is designed for the filling of canswith liquid through a singlesmall perforation in one end of each can when the can is in an invertedposition, that is, with the end or head having the single smallperforation lowermost. f

lVhile theymachine is adapted to fill cans with different kinds ofliquids, it has especial adaptability for illing cans wit-h milk in theform known as evaporated milk Where the milk is considerably thickenedby driving off a large proportion of the Water naturally found init-hemilk, the resultant product being, therefore, of a thicker consistencythan normal milk.

-It is found advantageous to prepare the cans into which the `milk is tobe introduced, such cans being customarily tin cans, with both heads in'place and thecan completely sealed with' the exception of a single small.central perforation m one head, such per-- foration' approximatingone-tenth or one'- eleventh of an inch more or less in diameter thereby`facilitating the final sealing with a minimumquantity of solder withoutliability of the solder flowing through the opening and dropping intothe can. This man- -ner of sealing the cans has been found inpractice-to be highly advantageous in the' mat-ter of rapidity ofsealing, certainty of sealing, anda economy inthe use of solder. Ithasbeen proposed to fill cans of the character described with evaporatedmilk` by introducing the milk through a Vsmall tube of a size and solocated as to enter the small perforation when uppermost and ,stillleave room about the tube for the escape vofi air from the can as. themilk tlows thereinto. This has been -found to be open to objectionbecause of the liability of foaming thefmilk" if sufficient force. beapplied to cause the '-tilling of the cans within a reasonable time, andmoreover, there is a liability of depositi-ng a -quantity of themilkabout the filling opening so as to require the cleansing-of the top ofthe can before the solder can be applied.

ln order to overcome the liability of foaming the milk While stillobtaining a rapid infiow of the milk into the can, a method has beendevised by me which consists in filling the cans While in an invertedposition, whereby the inflowing milk must pass through the body of milkalready in the can' so that. no distinct stream of milk can beformed,.for the milk, though enterin the can with the requisiterapidity, sprea soul;- therein toward the sidesvof the can under theaction of milk already within the can, this conditi'on arising almostimmediately after the filling operation begins. To accomplish the:filling `of the cans while in the inverted position l have devised twomodes of operation, one consist-ing in feeding the milk to the smallperforation under superatmospheric pressure while they.- air entrappedwithin the can because ot' its inverted position is allowed to dow outthrough a small tube from what in the filling operation constitutes the'upper end of the can, such-end of the can belng impor-- forate. Thismode of filling the can is disclosed in my application Serial No.634,052, filed J une 19,1911, for can filling apparatus. The other modeof lilling the cans While in the inverted position through the smallfilling,perforationconsists in withdrawing the air from the upper orimperforate end of the can by suction or the product-ion ofsubatmospheric pressureY therein, while the milk is forced into 'the canaround the suction tube by the action of atmospheric pressure due to theproduction of subatmospheric pressure within the can. This second modeof filling the cans is disclosed in my application filed June 19, 1911,Serial No. 634,051,

`for can filling apparatus, It is to this-second mode ot' filling thecans thatthe present' invention particularly relates.

ln accordance with the present invention l there is provided, in amachine of commercial capacity, a rotatable carrier for' the cans to befilled upon which the cans are placed in fthe inverted-position, thatis, lwith the perforated ends of the cans downward and the imperforateends upward. .Each can may have an individual support and related tothis support is an air tube of minute diameter, being commonly aboutone-thirtieth' of an inch internal diameter7 although the invent-ion; isby no means limited to such specnicgliameter. The cangsupport orcarfiez? is provided with n, can mg having; a. pafssage txsrtumwgTangled ha when bmnght against ,im formed can head ihm@ is pi'oducafl imwir the Csm.

The packing gland permits therotation of the neck?, while the pipe 16'is held against rotation, andat the same time prevents leakage at the junction.

Fast on the neck 7 is a worm gear wheel 23 driven by a Worm on a shaft26 journaled on columns 27 erected on the floor or other support for themachine, and this shaft is provided with a pullc 28 whereby power may beapplied to the s raft throu h the pulley 28l by means of a suitable bet. It will be understood, of course, that the pulley 273 may beconsidered as typical of any source of driving power, such, forinstance, as a direct connected electric motor. By means of theindicated orother dri-ving gear rotative movement is imparted to theneck 7 cylin- 'der 8 and shaft 5 and parts carried thereby,

which parts are hereinafter described. The upper end of the shaft 5 isformed with a flange 29 carrying a packing gland 30 engaging the flangedend of a pipe 31, which latter may remain stationary while the shaft 5rot-etes, and this provides means whereby any'suitahle air ex austingapparatus may be connected to` the interior of the hollow shaft 5 andthrough the latter tothe chamber lll. y

' Mounted on the shaft 5 is a spider 32 ter- Initiating in a peripheralring 33 to which is Vsecured a circular series of individual can baskets34, each comprising a plate like member 35 having `at one side.' acurved guard 36 which may be formed in one piece with the plate 35,andthis guard'has formed thereon a bracket 37"having atthe end re.

mote from the guard an angle' lip 38 de? signed to be traversed b one ormore bolts 39 by means of which t e can basket is secured to the spider32. The plates 35 may he, and preferably are, substantially segmental,so that the peripheral edge of the.

The plate 35 should at all times have a4 substantially constant positionwith respect to its height above other4 'parts of the machine, but the'height of the cans to be filled with milk may vary considerably.11i-Fig. each can is receired'npon la plate 35 and then in --thesubsequent operation ot the machine is elevated a' short distance until.its

block is a passage'fS.

movement is arrested by engagement with a stop or abutment, although theri 33 if suticiently extensive as in Fig. 17 wi l serve as a stop orabutment, but to adapt the ma-l chine to cans of different heights anddiameters lthere are provided the means illustrated in Figs. l1 to i4,Where each'bracket 37 has projecting therefrom on the side opposite theylip 38 a plate 40 constituting a stop or abutment and so related to theplate that a can such as 'indicated at 41 may be received uponthe plate35 and subsequently elevated to be arrested after a limited elevatingmovement byengagement With thev plate '4.0, the elevating movement beingpractically the same for the cans of different heights, since the plate40 is formed nearer to or farther from the late 35 in accordance withthe can to be utilized. So far as the baskets, carriers or holdersforthe cans are concerned, the machine is quickly adapted for any chosensize of can, by changing the can baskets which may be'accomplished bysimply removing the screws 39, the holes through the lips 38 and in thering 33 for the screws being the same' with all can basr kets, and thecan baskets for the different sizesof cansvbeing all so related that theperforated ends of the cans when on the baskets will have the samerelative position with respect to the other operating parts of themechanism. Since the smaller cans are of less diameter than the largercans, the guards 36 foi the small cans are made thicker than the guards36 for the larger cans, or are otherwise arranged to position' theperforations in the ends of thejsmall cans into the same relation to thesupports 35 as those of the lar er cans.

Each plate or tab e 35 is formed on the face remote from thatdesigned'to receive acan with aeck ,42, the interior walls of plate ortable 35, while that end t the necky 42 remote from the table 35 may eformed with an inturned flange 44 ot Vsmall radial extent, leaving apassage l5 throu h the said end of the neck. When the mac ine isinstalled `the brackets 37 are independing relation to the supportingspider 32 and the plates 35 are 'approimately horizontal and below thespider 32, while the necks 42 .are in depending relation to the plates35.

Lodged Within each neck 42 is a block 46 preferably cylindrical inoutline, the interior of the neck 42 being also cylindrical, althoughboth the neck and the block may be otherwise shaped. At an intermediateitil@ point the block ,a6 is formed with a circular groove 47ar'idextendi axially through -the ntering the passage 43 throuV h thelgroove 47 is a pipe 49 appropriately ent so as to extend through anotch 50 in oneside' of the block, and from thence in parallel relationto the longitudinal axis cy 'thc main portion cf flic 'mck cf thc :23Tmais abou c. gmdc the perforation 65 about the tube 64 into the can. Byproperly y proportioning the machine and the speed of movement of thecan support, the milk will tlow `into the can until it reaches the topof the tube 64, when any excess of milk will flow into" the tube 64'andfrom the latter into the cup 66 and ultimately through the ipe 77 intothe chamber 14. Finally the rol'er 92 reaches the terminal portion 93 ofthe track and under the` impulse of the spring 98 the cup 66 movesquickly downward until arrested by the engagement of the roller 92 withthe section or rail 95. Th`e tube 64 is, therefore, withdrawn with greatrapidity from the can and the seals at the gaskets 53 and 55 aresuddenly broken,` thev seal at the gasket 53 breaking first because ofthe greater compression of the. more' elasticA gasket 55, whereforethere remains' a condition of subatmospheric pressure Within 'the canclose to the imperforate head thereof which tends to pull in any slightquantity of milk which may gather about the perforation 65, while theaction of gravity upon any milk which may be within the passage 48causes the same to return to the trough 57. The inrush of'milk and airto relieve the subatmospheric pressure within the can also tends toclean the tube 64, so that it does not leave a quantityhof milk aboutthe perforation 65. Experience has shown that the perforation 65 is leftsufficiently clean for the application of solder without furthercleansing, the solder sticking tenaciously, and the passage 48discharges vbu't'a very few drops of milk onto the top of theplug 67?,

When the machine is set foramertain size can and it is desired to changethe machine for another size of can, the baskets 34 then in use areremoved from the spider 32 and the proper other set of baskets 34 aresubstituted. This lwill cause the tubes 64 to be either too short or toolong in accordance with whether the new set of baskets are for longer orshorter cans, and hence the tubes 64 4are adjusted as to their effectivelength by loosening the nuts 72, slipping the tubes lengthwise and,again tightening the nuts, when the'machine is. ready for operationwith the larger or smaller size of can, for which the machine isadjusted.- Y

With the inverted can the milk flows into the can without liability offoaming, but ifV thel difference between .the sub-atmos- .suing phericpressure within the can 'and the atmospheric pressure urging the milkinto the can -be great, there is a liability of the inlowing stream ofmilk forcingfits way through the bodyot milk in a manner to spurt abovethe surface of the mglk within the can and producing an efect which maybe described as geysering. Since thereis no adhesion or capillaryattraction between air and the walls of the small tube employed 7 as anexhaust tube within the can@ the air Hows out through the tube veryreadily, but the milk, because of the capillary size of the tube Get,flows sluggishly therethrough. Therefore, if the' rising level ot' themilkv withinpthe can be locally elevated to any considerable extentadjacent the' tube 6e, the milk will pass into the `tube long before theproper filling level yhas been reached and theretardin action of thetube upon the o utow o milk through it will result in prolonging thefilling operation very ma@A` terially. When thepressure is too geysersometimes forms closely adjacent to the tube 64@ and again will beproduoedat some little distance therefrom, so that: the

great the" rst instance the filling operationi"w srecans alike, themachine'm'ust beso operated.

as to correspond to the slowestv time oflling, wherefore if geyseringbe' presentthe more quickly filled cans "will overowl`into" the exhausttubes for afmaterial time before those cans which are more sluggishin'have'. received the full amount. of milk. l

Experience has ,demonstrated that with short cans, which approximate twoand-ouehalf inches in height, a degree of partial' vacuumcorrespondfingto six or seven inches ot the mercury vacuum gage, or as it is commonlyknown, six or seven inches of vacuum, causes a suliiciently vrapidinflow of milk without producing the geysering 'action and the risingmilk has a surface" very nearly level when it reaches the top of theexhaust tube.V It is not impracticahle to use 'a higher degree ofpartial vacuum, but it is not advisable to use any higherd gree olivacuum than will cause the milk to l ow into :the'c'an in a sufficientlygentle manner to prevent the milk from exhaust tube' because of itsforcible. syn-ranke into the can, thus choking the,"sulla(ist tubetemporarily until the suction clears it from the milk lentering it. Whenthe degree of vacuum is 'comparatively low the cans fill very closely touniformity as to time of illing, so that the operator may set the solutetime of filling, thus limiting to a minimum the amount 'of milkthatultimately passes through. the exhaust tubes geyseringv or spurting up`ouea,'the,

The pipes 77 are replaced bysmaller pipes 7 7 which at the ends enter the chamber 1l and cup 66,respectively, and by extending these pipes through rubber gaskets 107,as indicatedrin Fig. 15, a ilexibility of union is provided which willpermit the pipes 77 a to move up and down without the cups. The gasket107 is held -in place by a gland 108 screwed on ',to the nipple 109which in Fig. 15 is shown as entering' the cup 66 and the same structuremay be employed with relation to thev chamber 14. In' lace of theslotted strips 61 the reservbir nk 57 carries an upstandingl guide ring110 having upright slots 111 therein for the passage ofthe pipes 77h1and for lthe passage of arms 112, each of which at one end is connectedto an arm. 76u formed o-n the cup 66 and similar to the arm 76 of thestructure shown in Fig. 1 and associated tigures. The chamber 14: in thestructure shown in F ig. 17 is provided with acoverl -ntember 11a whichmay be formed 1n one piece with a shaft 5 similar to the shaft 5,

except that the shaft 5a maybe solid.

Around the margin of the cover 11a there is formed an annular groove 113and applied to the cover l1a is a ring 114. having a groove matching thegroove 113, while those ends of lthe arms 112 adjacent the axis ofrotation are each formed with a disk shaped terminalportion 115 adaptedlto the groove 113 and the matching groove in the ring 114. In machinescontaining a large number of filling elements, which number may inpractice range 'frornseventy' to one hundred forV each machine, the diskends 115 may' be brought into side contact, -as indicated in Fig. 16, sothat each arm is guided and held in position by the arms on both sides,while the disk like terminal portionsll act as `pivots for the arms,vpermitting the up'and A' and this pipe'leads to one end nf the air cyl*l4down movement of the cups 66 and associated parts.

The pintle 121 carries a roller 92 adapted to the track 89. lnorder to provide for vthe upholding of the cupv 66 and associated partsWhen, because of a non-in verted can, it passes through the gate 96,there is provided an annular ring 124 secured by brackets 125 to thering 110 and the angle extension 119 of the arm 77zt has toe portion 126adapted to ride on the ring 124 under the circumstances assumed. Theslots 111 are simple guiding slots and it is slots should sustain thecups. 66, since the Vtubes 77aare usually too delicate to Withstandundue Wear or shock. ,w It 1s unnecessary to describe -in detail theoperation of the structure shown 1n Figs.

17 and 18 so-ar as the filling of cans is concerned, since thatoperation is the same as that already described with reference to thestructure of Fig. l, but the adjustments shown in Figs. 17 and 18 andthe adjustment of the track shown in Fig. 1 provides for any shorteningof the gaskets 53and55 by repeated compression, such nozzles sometimesobtaining a permanent set, sov that un` less the parts be adjusted tomeet `-the changed relations leakage would occur.

In Fig. 15 the tube 64 is carried by a plug 67*1 through theintermediary of a screw bushing 127 Which inay be locked in place by alock nut 128 applied to the bushing, so that the eiieotive length of thetube 64 may be varied, as desired, and in the particular structure showntubes 64 of di'lierent lengths may be provided for'the diilerent sizesof cans, so that on the changing of the can baskets corresponding tubesmay be employed to loring'the open ends of thetubes linto properrelation Vto the closed .ends of the cans.

The can baskets have been described as separate structuresseparatelyapplied and removable, but it is evident that these parte maybe all cast in one and that other parts which are described as piece orin groups,

separate structures may be dilierently con structed. y y
